Application filed March 18, 1885. (N model.)

To aZZ whom it may concern.-

Be it known that we, HENRY A. HENDER- SON, of Lynn, in the county of Essex and State ofMassachusettsand FREEBORN F. RAYMOND,

5 2d, of Newton, in the countyof Middlesex and said State, citizens of the United States, have invented a new and useful Improvement in Heel-Nailing Machines, of which the following is a full, clear, and exact description,'ref- 1O erence being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement upon that described in the Patent No. 252,215, granted Henry A. Henderson, dated January 1?), 1882;

and it consists in the devices for automatically turning the revolving head, described in said patent, during the reciprocation of the crosshead and for automatically locking the revolving head, so that the various devices which it carries shall register with the other devices with which they co-operate in the process of attaching heels to boots or shoes.

Referring to the drawings, Figure 1 represents in front elevation, the jack and shoeguides being removed, the upper portion of a National heel-nailing machine having our improvement. Fig. 2 is a view in elevation of the right side of the machine. view in perspective of a portion of the device for turning the revolving head and for holding it locked in registering position. Fig. 4 is a vertical section upon the linexx of Fig. 1. Fig. 5 is a view in vertical section and in elevation in front of the line y y of Fig. 2. Figs. 6 and 7 are views similar to that of Fig. 3, showing other positions of the revolving head in relation to the turning devices.

The construction of the National heel-nailing machinehas been fully described in the various patents granted the applicants, and we will but briefly mention the parts which have been before described in these patents.

A A are the side frames of the machine. B is the bed, which supports the jack (not shown) and the post B.

O is the table or carriage,which is vertically movable upon the upper portion of the post B, and which supports the templet-plate'and Fig. 3 is atemplet 0 and the nail-holder plate and nail holder and carrier 0'. The templet-plate and templet are secured in suitable ways in the upper surface of the table or carriage by the side plates, 0 and the nail-holder plate and nail holder and carrier are arranged to slide upon the templet-plate. They are shown as automatically moved into and out of operative position-the templet and templetplate by the lever 0 pivoted at c, and operated by a cam,(not shown,) and the nail-holder plate and nail holder and carrier by the lever 0", pivoted at c, and operated by a cam, (also not shown;) but the cams operating these levers, and the conditions which govern the construction and operation of this part of the invention, are fully shown and described in the patent granted .Freeborn F. Raymond, 2d, dated December 11, 1883, No. 290,109.

D is the cross-head of the machine, which carries or supports the revolving head E. The cross-head D is reciprocated by means of the rods d and the connecting and operating mechanism described in the said Henderson 1 patent, or any equivalent mechanism. The head D has a space or opening sufficient to permit of the revolution of the head E therein, and it has a projection, 01, on one side, and 61 upon the other, to increase the thickness of the head in order to furnish suitable thickness for the bearings of the shaft 0, to which the revolving head E is fastened. This revolving head E has a number of arms for supporting a variety of operative devices. In the drawings it is shown as adapted to have three arms, one of which, the arm 6, supports the block 6 holding the gang or group of awls 6 the second of which, the arm 6*, supports the block 0 which carries the gang or group of drivers 0, and the third of which (not shown) supports the spanker-block, which has the top-lift attaching or holding devices socured thereto.

Attached or fastened to the front end of the shaft is the plate F, and this plate has three arms or extensions, f, f, and f (See Fig. 5 and in dotted lines in Fig. 1;) Each of these arms or extensions supportsi'a- 'cam-pin, the arm f supporting the cam-pin f the arm f supporting the cam-pinf, and the armf supporting the cam-pin f and each of these pins has an anti-friction roll thereon. The pins, it will be observed, are equidistant from 5 each other and from the center of the shaft 6.

Immediately in front of the cross-head andbolted to the side frames, A A, is the yoke or cross-plate G, and upon the inner surface of this plate, midway its length, there are ar- IO ranged the outwardly extending parts or guides g 9. (See Fig. 3.) These parts or guides are preferably cast with the plate, and they are shaped toprovide the vertical guiding-passage 9 the inclined guiding-surface 9 upon the part 9, and the rounded surface 9* upon the part 9. This central guiding-passage or space, 9 is of a width to receive the campins upon the plate F, and it is so arranged as to be opposite the vertical central line upon which the shaft 6 of the revolving head travels. Arranged immediately over these parts 9 and g, and attached to the plate G, so as to be movable horizontally thereon, is the switch or guide H. It has the slots h and h, through 2 which pass the headed studs h which hold it to the inner surface of the plate G, provide the rests or the guides upon which it is hori zontall'y movable, and they may form stops for limiting the extent of its movement. The un- 0 der surface of this switch or guide is curved downward on each side to the point if (see Fig. 3) to form a guide, and it is given a horizontal movement at predetermined intervals by means of-the cam-groove h in the plate if, 5 which is bolted or fastened to the cross-head D, to be vertically movable therewith, and the'cam-pin h, which extends from the arm h of the switch or guide block H, as shown in Figs. 2, 3, and 4:.

o Arranged at one side of the switch or guide block and the part 9 is a locking and guiding pawl, M, the arm m of which preferably is bent to bring its upper end, m, (at which it is hung or pivoted to the plate G by the pivotmfl) over the outer end of the part so that the pawl, by gravity, when pressed away, as hereinafter specified, returns automatically, and

so that the edge or surface m will shut against the outer edge of the upper portion of part ;As, however, it is not always expedient to trust to gravity for operating the pawl, we have used for returning it to the position shown in Fig. 3 the spring m. Another spring, m is also shown for the same purpose,

and one or both of them may be used, if desired; or, in lieu of the springs, any mechanical equivalent therefor for returning the pawl to said position may be used. The surface in of the pawl is curved outwardly and downwardly from the portion in, as shown, and the surfacem of the pawl is curved inwardly and upwardly from thepoint m, and in substantial continuation of the surface of the part Having now described the various parts of 6 5 the device forautomatically turning. and looking the revolving head, we will now explain the operation thereof.

Supposing the cross-head to be in its highest position, and reference'is especially made to Fig. 5 to show the position which the parts bear to each other when the cross-head is in its highest position, then the cam-pin'f is represented as at the upper end of the guiding-surface g and upon the downward movement of the cross-head D and of the revolving head this campin is moved along the rounded or inclined surface into the vertical recess 9 and the revolving head turns from the beginning of this movement until the descent of the head has brought the cam-pin f at the upper end of the vertical guidingpassage 9 when the revolving movement is stopped and the revolving head held locked by the vertical portions of the guides g and g, as one of the operative parts upon the revolving head has been brought into registering positionand we-will suppose that it is the awls and the cross-head continues its vertical movement with the revolving head locked.. (See Fig. 5.) After the cam-pin f has passed into the vertical passage g the switch and guide block H is moved laterally or horizontally by the upper section of the cam 71. so that the point It is moved into contact with a point upon the guiding-surface g at about the point a. in Fig. 3, and this movement closes the lat eral passage by which the pin f entered the vertical passage g". (See Fig. 7.) With this change in the position of the switch and guide block upon the upward movement of the crosshead and of the revolving head the pin f will pass upward in the passage 9 and will, by coming in contact with the curved surface a of the switch and guide block, be caused to move in the same direction as it was moved when it entered the vertical passage 9, and this of course will again begin to turn the revolving head, and this turning movement is continued during the-remainder of the upward movement of the cross;head. Meanwhile this turning of the revolving head has brought the pinf first, to a position immediately below the lower end of the pawl M. (See Fig. 7.) Upon the upward movement of the crosshead and upon the turning of .the revolving head, this cam-pinf then comes against the curved surface m of the pawl or latch M and moves it outward until it has passed beyond the portion m when the pawl or latch auto matically returns behind the cam-pin, as shown in Figs. 1 and 5, and throws it upon the upper surface of the guide 9 so that at the end of the upward movement of the crosshead the cam-pin f has been moved to the position which at the beginning of the downward movement had been occupied by the cam-pin f Meanwhile the pinf has been moved to the position which was occupied by the cam-pin f in Fig. 5, and the revolving head has made a third of a revolution. It is apparent from what we have said that each cam-pin is brought successively into the posi- IIO tion of the cam-pin f Fig. 5, and that it then moves as the cross-head is moved downward byrlocking the revolving head automatically when it has reached a certain position in its downward movement, and in maintaining it in the locked position until it has returned to that position; also, that the revolving head is moved or turned during the upper portion or part of the vertical movement of the cross-head.

It is obvious that four, five, or even six cam-v pins can be used in lieu of three, and that when more than three are used a complete revolution of the revolving head is made in as many reciprocations of the cross-head as there are pins. For instance, if there are four cam-pins employed, then it will take four reciprocations of the crosshead to cause the revolving head to make one complete revolution. If there are five cam-pins employed it will take five .reciprocations of the cross-head to' cause one complete revolution of the revolving head.

The switch-block is heldlocked by the cam h at all points of its movement, so tha i movement is dependent upon the shape of the cam, and when it has been moved over to bring the point If in contact with the guidingsurface it will be seen that the surface a of the switch-block bears such relation to the guidingsurface 9 that each cam-pin as it moves downward thereon comes in contact with the surface a and moves the switchblock horizontally, so as to permit the passage of the cam-pin into the straight passage, and so that the lower part of the surface a shall act as a guide or barrier in preventing the cam-pin from passing beyond the vertical passage. The lateral movement of the switchblock is commenced by the cam-pin,and causes the cam-pin of the switch-block to be moved into the portion a of the cam, and having entered the same this section of the camthen controls the movement of the block, so that it is moved laterally to open the downward passage g to the vertical guiding-passage and immediately returned positively to close it, and it is held locked in this closed position by the straight portion of the cam h. It will be seen that the throw of the switch-block takes place on the downward movement of the cross-head, and that when the cross-head is in its lowest position the switch-block cam-pin h is in the upper end of the straight passage of the cam groove, and that it remains in the straight part during the entire upward movement of the crosshead.

In operation the boot or shoe is placed on the work-support or last and moved into operative position, and the heel-blank placed thereon, the templet being over the heel-blank.

A reciprocation of the machine brings the awls into operative position and centers them in relation to the templet and holds them locked during their downward movement, and upon the upper end of the stroke the awls are moved out of position, and the drivers advanced to a position from which upon the next reciprocation of the machine they are moved into operative position, held locked, and moved as were the. awls. Upon a third reciprocation of the machine the spanker is brought automatically into position and centered and held locked, as were the awls and drivers, and the revolving head at the end of that movement will have made one revolution. Meanwhile the templet and nail-holder plates have been moved into and out of operation at proper intervals, and, if automatically, as described, the three reciprocations of the machine follow each other successively with no intermission or stop between.

Having thus fully described our invention, we claim and desire to secure by Letters Patent of the United States 1. The combination of the reciprocating cross-head D, the revolving head E, its shaft 6, the plate F, having cam-pins, as specified, and the turning, guiding, and locking device described, adapted upon each reciprocation of the cross-head to partially turn the revolving head and then to hold it looked, all substantially as and for the purposes set forth.
